We go to Disneyland in California every Christmas, but we will be taking a trip to Europe and thought we would stop for a day at Disneyland Paris. I have been on the website and am now totally confused, so I thought I would ask some DLP veterans for help! We can only go for 1 day, and I am targeting Tuesday, July 16th as this fits in with our other plans. We will have a car. I am trying to determine: If there is a significant advantage to staying onsite (i.e., are the early morning entry hours that essential to justify the cost? We are early risers and always open the park, but it would have to be Cheyenne or the Ranch for budget reasons.). If so, is it even possible to stay for two nights but only get a 1 day ticket? Everywhere I look they want to sell me at least a 2 day ticket. Do they enforce fastpass return times at DLP? (These are not enforced at Disneyland California....yet. It would changes the overall strategy for avoiding lines; just want to know what I'm getting into). Thank you so much in advance for your help.
